These Earth Therapeutics blending sponges feature purifying bamboo charcoal to help neutralize toxins and impurities. The purifying bamboo charcoal is embedded into the sponge and does not "come off" with use. Use with foundations, concealers, mineral and cream-based makeup. Easy elliptical, rounded shape allows for smooth application and blending. Non-latex polymer material is hypoallergenic safe. Soft and luxurious to the touch, sponges mold sensitively to the contours of the face. HOW TO USE Wet sponge in lukewarm water until saturated. Squeeze out excess water and apply your makeup. To prolong use, rinse thoroughly with warm water and store in a dry place. 2-pack Size: One size. Color: Black. Gender: Female.
